C-SPAN Video Archive of House and Senate Floor Proceedings
C-SPAN has created a video archive House and Senate floor proceedings. The new C-SPAN Congressional Chronicle is produced through a automated matching of the video recordings with the Congressional Record soon after the Record is available in the day following the session. Browse by date, bill number, or person's name. Looks like there is even a RSS feed for each representative.
Each appearance has both the text from the Congressional Record as well as a video link where users can watch and listen to the actual remarks. Only actual appearances by Representatives and Senators on the floor are included.
Currently the 108th (2003-2004), 109th (2005-2006), and 110th (2007-present) Congresses are available. The 107th (2001-2002) will be available soon and the 106 (1999-2000) in late 2007. Previous Congresses back to 1988 will be added as the video is digitized and indexed at the rate of two Congresses per year.
